Population and Critical Infrastructure Modeling

High-Resolution Population and Social Dynamics

Research in this thrust area includes algorithm and model development relating to high resolution spatiotemporal mapping of population, socio-economic indices, and population-infrastructure dependency. Current research and projects incorporate a variety of modeling techniques, disparate data integration, pattern recognition techniques, and complex statistical analysis of demographic data using high performance computing. Landmark products developed as part of this research include the LandScan USA and LandScan Global Population Databases.
